Pwm ripple

Tīmeklisprovides a near constant current source with only marginal ripple. • PWM driving: A common way of modulating the current is to pulse current through the load, then keeping the peak current constant and varying the ON and OFF duty cycle to make the average current change. This is commonly referred to as PWM driving. Tīmeklis2."micro DC/DC"コンバータの構造と特徴.
